Specicaton of Letters Patent.

Patented Nov. L1, 1919.

Application filed May 19, 1915. Serial No. 29,087.

To all whom t may concern:

Be it known that I, FRANCIS J. PLYM, a citizen of the United States, residing at Niles, in the county of Berrien and State of Michigan, have invented a new and useful Improvement in Thresholds, of which the following is a specification.

This invention relates more particularly to thresholds or constructions immediately under a door or window, and has for its object a new and useful threshold and a cooperating shield to be carried by the door or window, designed for the purpose of keeping out snow, rain, wind and the like.

Other features of novelty, advantage and capabilities will become apparent from the detail description of the accompanying drawing, in which there is illustrated a practical embodiment of the invention. It will be understood, of course, that the construction there shown is illustrative only, and not as defining the limits of the invention.

Figure 1 is an end elevation of a construction embodying the invention.

Fig. 2 is a perspective view of the threshold plate.

Fig. 3 is a similar view of the coperating shield carried by the door or window. Referring to the drawings in detail:

'The threshold plate 10 is constructed of sheet metal, preferably brass, having its upper surface corrugated or ribbed, and rests at its center on a suitable shelf or support 11, with its outer edges, which are curved outwardly and downwardly, fixed to the sill by means of screws 12. The upper edges of the threshold plate are bent inwardly, thence outwardly to form a groove 13 adapted to receive the lower curved edge 14 of the shield 15, which shield is carried copies of this patent may be obtained for ve cents each. by addressing the bythe door or window, when the door or window is closed, as a result of which rain, snow, wind and the like are prevented from passing through between the bottom of the door and the threshold plate. The shield 15 is secured to the door or window by any suitable means and is at its upper end provided with a downward and outwardly inclined drip member 16, which tightly engages the door or window and thus prevents rain or the like from finding its way between the shield and door, and also to an appreciable eXtent, protects the screws utilized for securing the shield in place.

It will be further noticed that by providing corrugations or ribs on the upper surface of the threshold plate that the danger of one slipping on the threshold plate is materially lessened, and. further, that if water should find its way onto the upper surface of this plate, it cannot flow or travel through to the interior unless a sufficient quantity is forced through to fill all the corrugations.

I claim:

In a device of the class described, a sheet metal threshold plate provided with a corrugated upper surface having its ends bent inwardly to form a bead, thence outwardly and downwardly to form a resilient wing, and a shield having an outwardly and inwardly bent Harige adapted to frictionally interlock with thefbead 'on said plate.

In witness whereof. I hereunto subscribe my name to this specification in the presence of two witnesses.

FRANCIS J. PLYM. Witnesses:
